Tire tread



FIG. 1 is a fragmentary perspective view of a tire tread, illustrating the novel design;

FIG. 2 is an enlarged, fragmentary top plan view of the tire tread illustrated in FIG. 1;

FIG. 3 is an enlarged, fragmentary side view of the tire tread illustrated in FIG. 1, with the opposite side view of the tire tread being identical to that shown in FIG. 3;

FIG. 4 is an enlarged cross-sectional view of the tire tread illustrated in FIG. 1, taken generally along line 4-4 of FIG. 2; and,

FIG. 5 is a fragmentary cross-sectional view of the tire tread illustrated in FIG. 1, taken generally along line 5--5 of FIG. 2.

The broken line showing of sipes on the tread and shoulder block surfaces of the claimed design is for illustrative purposes only and forms no part of the claimed design. The irregular outer edges of the design shown in FIGS. 1-3 indicate that the tire tread is of indeterminate length. 

I claim the ornamental design for a tire tread, as shown and described.
